'Dialogflow CX $param not showing in agent text

I am getting into CX and have a simple agent going but I cannot get the agent to respond with my filled parameter.

I have a page that asks for @DrinkFrequency and @DrinkChoice, I see both get filled correctly when I test the agent and $page.params.status = FINAL takes me to my next page that says

So you drink $session.params.DrinkFrequency and prefer to drink $session.params.DrinkChoice

But the agent says exactly that, it does not replace $session.params.DrinkFrequency or $session.params.DrinkChoice with the values the user gave. I know it must be a simple issue but I have tried to write $session.params.DrinkFrequency in a few different ways and I looked at the existing tutorial bots and they also have it with just the $ sign. Am I not saving the user given value?

The page that gets the values has the two parameters and they ask for the value in their "Initial prompt fulfillment" field.

Screen of the page asking for the values with one selected

Solution 1:[1]

You're referring to the entity type, while the display name is the name of your parameter.

If you replace $session.params.DrinkFrequency with $session.params.frequency and $session.params.DrinkChoice with $session.params.preference it should work.
